DESCRIPTIO
The LTC^®1599 is a 2-byte parallel input 16-bit multiplying
current output DAC that operates from a single 5V supply.
INL and DNL are accurate to 1LSB over the industrial
temperature range in both 2- and 4-quadrant multiplying
modes. True 16-bit 4-quadrant multiplication is achieved
with on-chip 4-quadrant multiplication resistors.
The LTC1599 is available in 24-pin PDIP and SSOP packages
and is specified over the commercial and industrial tempera-
ture ranges. The device includes an internal deglitcher circuit
that reduces the glitch impulse to 1.5nV-s (typ). The asyn-
chronous CLR pin resets the LTC1599 to zero scale when the
CLVL pin is at a logic low and to midscale when the CLVL pin
is at a logic high.
For a full 16-bit wide parallel interface current output DAC,
refer to the LTC1597 data sheet. For serial interface 16-bit
current output DACs, refer to the LTC1595/LTC1596 data
sheet.
